BAB II
PENULANGAN PELAT 2 ARAH
A. PELAT T = 12.00 cm, BEBAN HIDUP = 250 KG/M2
I. DATA - DATA
- Tebal Pelat Lantai : mm
- Selimut Beton : mm- Mutu Beton (fc) : Mpa ( K - )
- Mutu Baja (fy) : Mpa ( Tulangan Polos )
- Diamater Tulangan Utama : mm
- Diamater Tulangan Bagi/Suhu : mm
II. PEMBEBANAN PLAT LANTAI
a. Beban Mati
- Pelat ( t = x ) : kg/m2
- Spesi ( t = x ) : kg/m2
- Plafon & Penggantung ( 7 + ) : kg/m2
- Keramik ( t = x ) : kg/m2
+
QDL : kg/m
b. Beban Hidup
- Beban Hidup Kantor : kg/m2
